The vulnerability exists due to a boundary error when processing HTTP/3 requests within the HTTP/3 QUIC module (ngx_http_v3_module). A remote attacker can send specially crafted HTTP/3 requests to the web server, trigger an out-of-bounds write and perform a denial of service (DoS) attack.
2) Use-after-free (CVE-ID: CVE-2024-34161)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a use-after-free error within the HTTP/3 QUIC module (ngx_http_v3_module). A remote attacker can send specially crafted HTTP/3 requests to the web server and read parts of free memory.
3) NULL pointer dereference (CVE-ID: CVE-2024-35200)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the HTTP/3 QUIC module (ngx_http_v3_module). A remote attacker can send specially crafted HTTP/3 requests to the web server and perform a denial of service (DoS) attack.
4) Stack-based buffer overflow (CVE-ID: CVE-2024-31079)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when HTTP/3 requests within the HTTP/3 QUIC module
(ngx_http_v3_module). A remote attacker can send specially crafted requests to the web server, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.
